Abstract
The invention discloses a preservative cabinet which does not need freezing for storage of fresh meat and meat products and is harmless in operation and maintenance. The preservative cabinet disclosed by the invention adopts nitrogen for refreshment and stores the food which easily goes bad in natural air by use of the steady chemical properties of nitrogen; and automatic preservation can be realized by use of a PLC (programmable logic controller). The preservative cabinet disclosed by the invention requires relatively high one-time investment, enables natural operation of all elements except some consuming power, and conforms to the low-carbon lifestyle; and the high-configuration preservative cabinet is suitable for refreshing a large quantity of fresh meat and meat products in a large scale, and the low-configuration preservative cabinet is economical and practical for household.
Description
Technical field
The present invention relates to a kind of antistaling cabinet, especially a kind of antistaling cabinet of fresh-keeping meat products.
Background technology
At present, mostly known antistaling cabinet is to utilize freon refrigeration, preserves meat and meat product at low temperatures, as everyone knows, freon is ozone layer 03 killer, is the arch-criminal of depletion of the ozone layer, in the later stage eighties, the production of freon has reached the peak, and output has reached 1,440,000 tons.Before freon was carried out control, the freon that discharge in atmosphere in the whole world had reached 20,000,000 tons.Because their average life spans in atmosphere reach hundreds of years, so the major part of discharging is still stayed in the atmosphere, wherein major part still rests on the troposphere, and sub-fraction rises up into stratosphere.At the freon of troposphere quite stable, after rising enters stratosphere, under certain meteorological condition, can under the effect of intense UV rays, be decomposed, the chlorine atom that decomposition discharges constantly destroys ozone molecule with ozone meeting chain-react.Scientist estimates that a chlorine atom can destroy tens thousand of ozone molecules.According to data, ozone cavity area had reached 2,500 ten thousand square kilometres in 2003.After a large amount of losses of ozone layer quilt, the ability of ultraviolet radiation-absorbing weakens greatly, and the ultraviolet ray that causes arriving earth surface obviously increases, and brings many-sided harm to human health and ecological environment.According to one's analysis, stratospheric ozone reduces ten thousand/, the global cataractous incidence of disease will increase 0.6-0.8%, promptly mean so cause that blind number will increase by 10,000 to 1.5 ten thousand people.
In living at home, reach in freezer adopts freezing mode to preserve meat products, and meat products when taking needs one period of spending frost owing to be frozen the hard of change, even and descending over a long time in freezing condition that meat products also can go bad, reach in freezer has brought inconvenience to people.
Summary of the invention
In the process of fresh-keeping foodstuff, use harmful substance freon in order to overcome traditional freshness preserving equipment, and fresh-keeping shortcoming and the drawback of use frozen food, the object of the present invention is to provide and a kind ofly in preservation process, do not use freon, and need not the antistaling cabinet of freeze preservation.
A kind of antistaling cabinet, storeroom is arranged, it is characterized in that antistaling cabinet adopts nitrogen to fill the interior space of cabinet, utilize the inactive chemical property fresh-keeping meat products of nitrogen, antistaling cabinet is by high-pressure nitrogen bottle, the nitrogen valve, airtight carrying case, the PLC control module, the Pressure monitoring instrument, getter device and branch compartment are formed, logical high-pressure nitrogen bottle of the nitrogen valve couplet on the door and antistaling cabinet, in antistaling cabinet, charge into nitrogen, airtight carrying case is the meat products in airtight minute compartment when taking, then getter device detaches the nitrogen in the branch compartment, carrying case is opened the back and is extracted meat products, Pressure monitoring instrument monitoring cabinet internal gas pressure, the result is fed back to the PLC controller, and the PLC controller is regulated the each several part duty, realizes automatic operating.
The invention has the beneficial effects as follows, utilize inactive chemical property of nitrogen to preserve meat products, environmental protection, adding the PLC control module, is to preserve and take the realization automation, getter device quote the use amount that reduces nitrogen to a certain extent, the disposable input of the present invention is lower, the meat products of comparing traditional freezing preservation of freon need not defrost and freezes step, promptly gets i.e. usefulness, makes things convenient for the user.
The specific embodiment
The present invention is further described below in conjunction with embodiment.
When using the present invention to preserve meat products, the nitrogen valve couplet on the door leads to nitrogen cylinder and antistaling cabinet in advance, in it, pour quantitative nitrogen, get rid of air wherein, control panel is set, the user can select a branch cell that article are put into it, airtight carrying case exports out selecteed minute airtight being sent to of cell after selecting, getter device detaches nitrogen in it, closed box is opened pore and is communicated with outside air in getter device operation, the maintenance inside and outside air pressure balance, and unlikely generation air blast damages the user, detach at nitrogen, air mend into after closed cabin open, the user extracts meat products, and Pressure monitoring instrument monitoring cabinet internal gas pressure feeds back to the PLC controller with the result, the PLC controller is regulated the each several part duty, realizes automatic operating.
Wherein, the steel cylinder that nitrogen cylinder adopts steel plate to make can suitably be chosen 2～10L specification according to actual amount, supports 2～20Mpa pressure, is fit to the requirement of the present invention to bomb.
Adopt contactor control air valve conducting state, the PLC Programmable Logic Controller is controlled the switch of air valve automatically, regulates the interior nitrogen content of antistaling cabinet within the specific limits.
Divide compartment and cabinet to adopt the safety glass material in conjunction with airtight measure, the transparency height can bear 1～1.5 times of atmospheric pressure, and can guarantee that the user differentiates article in the cabinet, meets requirement of the present invention.
Carrying case adopts trapped orbit slip load mode, divides compartment and public passage that track is set at each, and common-rail and outlet are provided with sliding rail.
